Add a Request Dispatcher and pass buildUrl as an argument, which has the url for the showItems.jsp page.
Forward to that request dispatcher to draw the JSP page.
Code snippet of the modified processRequest method is shown below.
Add Html and JSP Tags :
First import the following packages: au.com.tusc.cmp.*, java.util.ArrayList and java.util.Iterator.
Now add the necessary HTML and JSP tags to access items of MyStore.
Get itemsList from our session attribute set in servlet AccessController.
Set itemData as a page attribute via pageContext.
Now display the attributes of itemData using JSP property access tags. Code snippet for the showItems page is shown below.
Note : This JSP Page is a view in the Front Controller Pattern discussed above.
Now the JSP page is done.
Go to OnlineStore (web module) node > right click > select Lomboz J2EE.. on pop up menu > Check All JSP Syntax.
See if there are any errors.
Go to OnlineStore node > right click > select Lomboz J2EE.. on pop up menu > Add WEB-INF/lib JARs to the Classpath as shown below.
Deploy Module OnlineStore :
In order to deploy, go to LombozJ2EE view.
Select web module OnlineStore > right click > select Deploy module, make sure the server is running.
Deployment status will be visible on the console. If deployment is successful then test your JSP page.
Test your JSP Page :
Go to your browser and access the servlet using the following web address, 'http://localhost:8080/OnlineStore/access'
where 'access' is the url mapping that was assigned whilst creating the servlet in the Servlet Creation Wizard, and OnlineStore is the web module where the servlet AccessController resides.
The login screen will be displayed. Enter username as 'ANDY' and password as 'PASSWD'. The next screen will be the list of items in MyStore as shown below.
You have successfully created a JSP page using all the J2EE components, and they have been created and deployed successfully. Congratulations!
